Webservice exceptions

Hi guys,

currently I am stucked in my development of a webservice.

I used the Developer Studio for this, so what I did was developing a Session Bean and used the Web Service wizard to create a webservice on it. Finally I generated a proxy for my webservice and deployed all this on a netweaver application server.

Now when I try to access one of the business methods of the session bean via the webservice I get a SOAPFaultException. The full stack trace is:

Exception in method returnTestMessage. javax.xml.rpc.soap.SOAPFaultException: Exception in method returnTestMessage. at com.sap.engine.services.webservices.jaxrpc.wsdl2java.soapbinding.MimeHttpBinding.buildFaultException(MimeHttpBinding.java:735) at com.sap.engine.services.webservices.jaxrpc.wsdl2java.soapbinding.MimeHttpBinding.processDocumentFault(MimeHttpBinding.java:857) at com.sap.engine.services.webservices.jaxrpc.wsdl2java.soapbinding.MimeHttpBinding.call(MimeHttpBinding.java:1432) at com.sap.coe.webservices.openpms.Config1BindingStub.returnTestMessage(Config1BindingStub.java:154) at com.sap.coe.webservices.openpms.Config1BindingStub.returnTestMessage(Config1BindingStub.java:169) at jsp_TestOpenPMSWebService1182772339373._jspService(jsp_TestOpenPMSWebService1182772339373.java:62) at com.sap.engine.services.servlets_jsp.server.jsp.JspBase.service(JspBase.java:112) at com.sap.engine.services.servlets_jsp.server.servlet.JSPServlet.service(JSPServlet.java:544) at com.sap.engine.services.servlets_jsp.server.servlet.JSPServlet.service(JSPServlet.java:186) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.sap.engine.services.servlets_jsp.server.HttpHandlerImpl.runServlet(HttpHandlerImpl.java:401) at com.sap.engine.services.servlets_jsp.server.HttpHandlerImpl.handleRequest(HttpHandlerImpl.java:266) at com.sap.engine.services.httpserver.server.RequestAnalizer.startServlet(RequestAnalizer.java:387) at com.sap.engine.services.httpserver.server.RequestAnalizer.startServlet(RequestAnalizer.java:365) at com.sap.engine.services.httpserver.server.RequestAnalizer.invokeWebContainer(RequestAnalizer.java:944) at com.sap.engine.services.httpserver.server.RequestAnalizer.handle(RequestAnalizer.java:266) at com.sap.engine.services.httpserver.server.Client.handle(Client.java:95) at com.sap.engine.services.httpserver.server.Processor.request(Processor.java:160) at com.sap.engine.core.service630.context.cluster.session.ApplicationSessionMessageListener.process(ApplicationSessionMessageListener.java:33) at com.sap.engine.core.cluster.impl6.session.MessageRunner.run(MessageRunner.java:41) at com.sap.engine.core.thread.impl3.ActionObject.run(ActionObject.java:37) at java.security.AccessController.doPrivileged(Native Method) at com.sap.engine.core.thread.impl3.SingleThread.execute(SingleThread.java:100) at com.sap.engine.core.thread.impl3.SingleThread.run(SingleThread.java:170) 

I am not familiar with webservices (in fact this is my first project I am using webservices in).

So are there any experts here who can explain to me what this error means? What could be the reason for this exception?

Thanks for all answers!

Regards,

Torben
